Title:
CONCRETE BLOCK
Document Type and Number:
Japanese Patent JP2016155708
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a concrete block making it possible to sufficiently decrease the temperature of a block surface without using any heat blocking pigment.SOLUTION: A concrete block 100 has a concrete base layer part 60A and a surface layer part 60C formed on the base layer part 60A. The surface layer part 60C is composed of an aggregate Wb2 and portland cement. The aggregate contains not less than 50% of the aggregate Wb2, whose solar reflectance is 35% or more, with respect to the weight of the whole aggregate. An exposure processing for exposing the aggregate Wb2 on the surface of the surface layer part 60C is carried out so that the solar reflectance of the surface is 30% or more.SELECTED DRAWING: Figure 1
